# mkdir -p /opt/data/registry
# sudo docker run -d -p 5000:5000 -v /opt/data/registry:/tmp/registry registry

# docker images

registry latest d1fd7d86a825 3 months ago 33.3MB
google/cadvisor latest 75f88e3ec333 5 months ago 62.2MB 4、上传镜像到仓库
# docker push 10.0.0.143:5000/test
The push refers to repository
Get https://10.0.0.143:5000/v2/: http: server gave HTTP response to HTTPS client 报错说明：Docker从1.3.x之后，与docker registry交互默认使用的是https，但是此处搭建私有仓库却只提供http服务，所以当和私有仓库交互时报上述错误。因此需要在启动docker server时增加启动参数为默认使用http访问
5、解决方法：
# vim /usr/lib/systemd/system/docker.service
# ExecStart=/usr/bin/dockerd
ExecStart=/usr/bin/dockerd --registry-mirror=https://ag3w25ij.mirror.aliyuncs.com --insecure-registry 10.0.0.143:5000
# systemctl restart docker.service
Warning: docker.service changed on disk. Run 'systemctl daemon-reload' to reload units.

# docker push 10.0.0.143:5000/test
